After a brief search of the forums I did not find an answer so I am posting here. I have 3 2560x1080 monitors and when I use aero snap with keyboard shortcuts it has an extra position that appears to be the pixel difference between 1920 and 2560 is this intended behavior? The position is still snapped vertically but is approximately where a 1080p display would begin. It isn't a huge issue but it is annoying.

The windows key left/right arrow shortcuts.
